Mildly philosophical question: What if the guru has no shame? Then what?

I'm not naming names. Indeed, none specifically came to mind.

Well, shaming people is more fun if they actually feel ashamed. But if they don't, you still have the pleasure of feeling self-righteous. Usually, instead of feeling ashamed, they just get self-righteous right back at you. So everybody gets to feel self-righteous, and it's a win-win. Isn't the Internet wonderful?
